Best Free Database Management Systems (DBMS)

Xano is the unified backend for building and deploying production-grade apps and AI agents. Instead of stitching together databases, runtimes, APIs, auth, integrations, and monitoring—plus a separate orchestrator for agents—Xano provides everything in one secure, scalable platform. Teams can model data, compose logic, expose secure APIs, and integrate with any system, while AI agents can use data and APIs, call external tools, and run server-side with observability and guardrails. Build visually, with AI, or in code from your IDE, then deploy with one click and scale automatically. Xano works with any frontend, including Lovable, Bolt, WeWeb, Retool, and custom code, so you don’t need to rebuild as you grow. Compliance, reliability, and scaling are built-in, enabling teams to focus on the business logic that makes their software unique.

Ragic is a no-code database builder that allows its user to build their own system according to their own workflow with a spread-sheet like interface that is as quick and as intuitive, capable of building small contact management systems to fully fledged ERP systems.

StarTree, powered by Apache Pinot™, is a fully managed real-time analytics platform built for customer-facing applications that demand instant insights on the freshest data. Unlike traditional data warehouses or OLTP databases—optimized for back-office reporting or transactions—StarTree is engineered for real-time OLAP at true scale, meaning: - Data Volume: query performance sustained at petabyte scale - Ingest Rates: millions of events per second, continuously indexed for freshness - Concurrency: thousands to millions of simultaneous users served with sub-second latency With StarTree, businesses deliver always-fresh insights at interactive speed, enabling applications that personalize, monitor, and act in real time.

Xata is a combination of a relational database, an analytics engine, and a free-text search engine. All made simple by a spreadsheet-like UI and a single powerful data API, with granular security, zero-downtime migrations, subscriptions, ACID transactions, and caching built-in. If you don’t worry about servers when deploying your application, why should you worry about servers (or nodes, or clusters) when using a database service? The simple global RESTful API for inserting, querying, aggregating, and searching makes Xata the perfect companion for Serverless and No-Code/Low-Code development platforms. Xata allows you to iteratively build your database schema as you add sample data, all via a spreadsheet-like UI. You can add new tables, columns, data, and create queries and views. It then gives you code samples ready to be used in your application. This gives you flexibility as you develop and, as the application grows, the strict schema keeps your data safe and correct.

Turso is a globally distributed, SQLite-compatible database service designed to provide low-latency data access across various platforms, including online, offline, and on-device environments. Built atop libSQL, an open-source fork of SQLite, Turso enables developers to deploy databases close to their users, enhancing application performance. It supports seamless integration with multiple frameworks, languages, and infrastructure providers, facilitating efficient data management for applications such as personalized large language models and AI agents. Turso offers features like unlimited databases, instant rollback with branching, and native vector search at scale, allowing for efficient parallel vector searches across users, instances, or contexts using SQL database integration. The platform emphasizes security with encryption at rest and in transit and provides an API-first approach for programmatic database management.
